According to barstool - and the kids Dad, the kid was just having a go with the Syracuse fan... They laughed and took pics together, afterward...
One post I enjoyed on barstool(the one the Dad responded, to) LSU spelling/grammar
When I was young (probably around that kids age) I once booed Marshall Faulk after he in ran for a touch down. He looked up and pointed at me and he jokingly made this "haha to bad" gesture. So I gave him the thumbs down, and he gave me the thumbs up. I shook my head at him, and he laughed and smiled, and than tossed me the ball... And I still have that ball today, and it's one of the reasons why i grew up loving sports. And sports are what kept me out of other activities that could have gotten me in trouble.
